Volume expansion seems inactive
Hello, Volume expansion seems to be running for 2 days now but I have no sign of progress within the GUI. See the HDD sizes and the actual disk space. Something is wrong but I don't know what. So...
The screenshots aren't showing because images are reviewed by a moderator before they are published (just in case someone posts something inappropriate). Once a moderator approves them they will then show.
I can't see your screenshots, but what you are looking for is to see a resync with a percentage indicator of progress.
You can alternatively copy and paste the text from the output of
watch /cat/proc/mdstat
rather than post a screenshot.
The code tag option (see the </> button) is very good for posting that kind of output.
Say you are using X-RAID you would have md0 (4GB OS volume), md1 (swap) and md127 (data volume).
If you had say 3 disks installed and added a fourth you should see the 4th disk added to md0, md1 and md127. The md0 and md1 resyncs are very quick, but the md127 one would take a while.
If you replace a disk with a higher capacity disk, not only will md0, md1 and md127 need to be rebuilt, but if you have at least two disks of the higher capacity installed a new layer md126 would be added (note this is just an example md127 could be the new layer showing and md126 the one already present).
Once the resyncs have finished you should no longer see a rebuild status or percentage for any of the RAID arrays. The data volume should then expand provided your additions have met the requirements for expansion for the RAID level you have chosen.
If it doesn't expand you could see if a reboot helps.
I am afraid that's chinese to me.
I ran your command and got the screenshot enclosed. After reboot log says system is up and volume settings says status is redundant, appart from that the system totally disregards the amout of available space and is still stuck at a much lower value of disk space. No expansion. The GUI really lacks information.
I suppose my issue won't progress until the moderator unlocks my screenshots đ
That mdstat output does not show any expansion still ongoing. It shows you have four 3TB drives and two 4TB drives. Is that accurate? What was the previous configuration before the expansion? I'm afraid I don't recall all of the expansion limits of RAIDiator 4.2.x, but you may have run into one of them. mdgm or StephenB can help you more there.
There is some confusion in the answers because until the screen shots were shown, it was unclear if you were still running 4.2.x or had upgraded to OS6.
OS6 ? Is there an upgrade path to OS6?
Anyway. At the beginning I had 6 X 3Tb HDDs. Gradually for each that failed a 4 Tb HDD replaced it. Now I am with 3 X 3Tb and 3 X 4Tb HDDs.This KB will describe the limitations incl. for OS 4.2: https://kb.netgear.com/7010/ReadyNAS-Volume-Expansion
